Authenticity has never once been an issue at Chrono24 and we are extremely proud of our track record dating back many years and thousands of watches.

Every timepiece we buy and sell is carefully inspected by our in-house team of Swiss-trained Watchmakers and is certified authentic before being available for sale. With an in-house team of more than 10 Watchmakers, Technicians and Polishers and over 65,000 watches bought and sold over the years, authenticity has never been an issue for Chrono24.

We are committed to delivering watches in 'like new' condition where possible. We list the condition clearly in the product details section of each watch. Each watch we sell is first certified and—if needed--restored by our expert watchmakers, making an elegant timepiece that will command respect and admiration when worn on your wrist. Our watchmakers’ exacting standards and attention to detail, allow us to offer our watches at a condition that our competitors can’t match. We hold ourselves to the highest standards in the industry, and offer unbeatable prices for the quality of our merchandise.

Chrono24 will certify a timepiece as Authentic based on the following conditions:

1. Critical Components such as the Case, Case Back, Dial, Movement and Movement Plate are genuine and were produced by the original watch manufacturer;
   
   
2. Other Components such as Crowns, Hands, Bezels, Push-Pieces, Bracelets, and Straps that are subject to wear-and-tear may have been replaced over time (especially for vintage watches) but this is limited to no more than two components per watch and the replacements will be genuine parts produced by the original watch manufacturer; and
   
   
3. Especially in the case of vintage watches, items such as Movement Components (e.g., screws, wheels, springs, seals) and Crystals may be aftermarket and certified as long as they do not bear a trademark or logo.
   
   

Chrono24 will not certify as authentic any watches that have been customized or any watches with fake or counterfeit parts.
